Butch:

Well, unfortunately, I don't have a dummy load, and my recent experiences 
with my IC746 have convinced me that it needs to be the next thing on my 
shopping list.  Will probably go for one of those MFJ dry dummy loads.

The instructions for the supply don't say anything about the dangers of RFI 
getting into it, but common sense would suggest that that's something we 
don't want, so will see if I can determine if RFI is a factor at all.
